Any way to obtain the Chart object without importing Chart.js?

[bcl-lcb]

Here is my code:

import { Component, OnInit } from '@angular/core';
import 'chartjs-plugin-streaming';
import { ActivatedRoute } from '../../../node_modules/@angular/router';

@Component({
  selector: 'app-resource-monitor',
  templateUrl: './resource-monitor.component.html',
  styleUrls: ['./resource-monitor.component.css']
})
export class ResourceMonitorComponent implements OnInit {

  datasets: any[] = [{
    data: [],
    label: 'line1'
  }, {
    data: [],
    label: 'line2'
  }];
  options: any = {
    scales: {
      xAxes: [{
        type: 'realtime'
      }]
    },
    plugins: {
      streaming: {
        onRefresh: function (chart: any) {
          chart.data.datasets.forEach(function (dataset: any) {
            dataset.data.push({
              x: Date.now(),
              y: Math.random()
            });
          });
        },
        duration: 20000,    // data in the past 20000 ms will be displayed
        refresh: 1000,      // onRefresh callback will be called every 1000 ms
        delay: 1000,        // delay of 1000 ms, so upcoming values are known before plotting a line
        frameRate: 30,      // chart is drawn 30 times every second
        pause: false,       // chart is not paused
      }
    },
    animation: {
      duration: 0                    // general animation time
    },
    hover: {
      animationDuration: 0           // duration of animations when hovering an item
    },
  };

  constructor(private route: ActivatedRoute) { }

  ngOnInit(): void {
    this.route.params.subscribe(params => {
      const id = params['id'];
    });
  }

  pause() {
    this.options.plugins.streaming.pause = !this.options.plugins.streaming.pause;
  }
}

I want to start/pause the chart.
It seems like I need to update the chart after setting this.options.plugins.streaming.pause as true.
So I wonder if there is any way to obtain the chart object and call chart.update().

Thanks a lot!!!

Yes, that's what I did. Thanks!
